Dinámica no lineal de la regulación autonómica cardiovascular durante la prueba del peso sostenido en pacientes con diabetes mellitus tipo 2

Rev. colomb. cardiol; 28 (5), 2021
Resumen Introducción: La dinámica no lineal de la regulación autonómica cardiovascular a partir de la variabilidad de la frecuencia cardiaca no ha sido previamente estudiada en pacientes con diabetes mellitus tipo 2 mediante la prueba del peso sostenido como inductor de hiperreactividad cardiovascul...

Acute response to aerobic exercise on autonomic cardiac control of patients in phase iii of a cardiovascular rehabilitation program following coronary artery bypass grafting

Abstract Objective: The aim of the present study was to investigate the acute response to aerobic exercise on autonomic cardiac control of patients undergoing coronary artery bypass grafting (CABG). Methods: The study sample consisted of eight patients (age: 58.6±7.7 years; body mass index: 26.7±3.5 ...

Sympatho-Vagal Imbalance is Associated with Sarcopenia in Male Patients with Heart Failure

Arq. bras. cardiol; 112 (6), 2019
Abstract Background: Resting sympathetic hyperactivity and impaired parasympathetic reactivation after exercise have been described in patients with heart failure (HF). However, the association of these autonomic changes in patients with HF and sarcopenia is unknown. Objective: The aim of this study wa...

Women with Polycystic Ovarian Syndrome Exhibit Reduced Baroreflex Sensitivity That May Be Associated with Increased Body Fat

Arq. bras. cardiol; 112 (4), 2019
Abstract Background: Polycystic ovarian syndrome (PCOS) women have a high prevalence of obesity and alterations in cardiovascular autonomic control, mainly modifications in heart rate variability (HRV) autonomic modulation. However, there are few studies about other autonomic control parameters, such as...

Effects of a new approach of aerobic interval training on cardiac autonomic modulation and cardiovascular parameters of metabolic syndrome subjects

ABSTRACT Objective: To evaluate the effects of 16 weeks of periodized aerobic interval training (AIT) on cardiac autonomic modulation and cardiovascular parameters of metabolic syndrome (Mets) individuals. Subjects and methods: The sample was composed of 52 subjects with a diagnosis of Mets, allocated ...

The effects of cataract surgery on autonomic heart rate control: a prospective cross-sectional and analytical study

Clinics; 74 (), 2019
OBJECTIVES: We aimed to evaluate the effects of cataract surgery on cardiac autonomic modulation. METHODS: A cross-sectional and analytical study was conducted at the Hospital Maria Braido in the city of São Caetano do Sul, São Paulo, between 2015 and 2016. We investigated 19 patients of both sexes wh...

Autonomic dysfunction in patients with central serous chorioretinopathy

Rev. bras. oftalmol; 77 (6), 2018
Abstract Objetive: To evaluate the association between sympathetic nervous system activity and blood pressure variability with central serous chorioretinopathy (CSC). Methods: We performed an individual, observational, and cross-sectional study involving 11 patients with CSC and 16 healthy individuals ...

Effects of Coexistence Hypertension and Type II Diabetes on Heart Rate Variability and Cardiorespiratory Fitness

Arq. bras. cardiol; 111 (1), 2018
Abstract Background: Type 2 diabetes Mellitus (T2DM) is associated with cardiac autonomic dysfunction, which is an independent predictor of mortality in chronic diseases. However, whether the coexistence of systemic arterial hypertension (HTN) with DMT2 alters cardiac autonomic modulation remains unknow...

Complexity of autonomic nervous system function in individuals with COPD

J. bras. pneumol; 44 (1), 2018
ABSTRACT Objective: To evaluate autonomic modulation in individuals with COPD, compared with healthy controls, via recurrence plots (RPs) and linear heart rate variability (HRV) indices. Methods: We analyzed data on 74 volunteers, who were divided into two groups: COPD (n = 43) and control (n = 31). Fo...

ACE gene dosage determines additional autonomic dysfunction and increases renal angiotensin II levels in diabetic mice

Clinics; 73 (), 2018
OBJECTIVES: The present study aimed to investigate cardiovascular autonomic modulation and angiotensin II (Ang II) activity in diabetic mice that were genetically engineered to harbor two or three copies of the angiotensin-converting enzyme gene. METHODS: Diabetic and non-diabetic mice harboring 2 or 3 ...
